1. What is the Palm Method?

The palm method is a quick way to estimate burn surface area, where the patient's palm (including fingers) represents approximately 1% of their total body surface area (TBSA). This method is particularly useful for small burns or scattered burns.

2. How Does the Calculator Work?

The calculator uses the simple palm method equation:

Key Points:

• 1 palm = 1% of total body surface area (TBSA)
• The palm includes the fingers (entire palmar surface)
• Use the patient's own palm for most accurate estimation
• For larger burns, use the Rule of Nines for initial estimation

3. Importance of TBSA Calculation

Clinical Significance: Accurate burn surface area estimation is critical for:

• Determining fluid resuscitation needs (Parkland formula)
• Assessing burn severity
• Making decisions about hospital admission
• Guiding treatment plans

4. Using the Calculator

Instructions:

1. Count how many of the patient's palms would cover the burned area
2. Enter this number in the calculator
3. The calculator will show the percentage of total body surface area burned

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the palm method?
A: It's reasonably accurate for small burns (up to 10% TBSA) when using the patient's own palm. For larger burns, the Rule of Nines is preferred.

Q2: What's considered a major burn?
A: Generally, burns >10% TBSA in children/elderly or >20% in adults, or burns involving face, hands, feet, or genitals.

Q3: Should I use my hand or the patient's hand?
A: Always use the patient's own palm for most accurate estimation, as hand sizes vary.

Q4: How does this compare to the Rule of Nines?
A: The Rule of Nines divides the body into sections worth 9% or multiples (good for large burns), while the palm method is better for smaller or scattered burns.

Q5: When should I seek medical attention for a burn?
A: For burns >1% TBSA in children, >2% in adults, or any burn involving face, hands, feet, genitals, or circumferential burns.
